Complex timing. Write a Stopwatch client that compares the cost of using Complex to the cost of writing code that directly manipulates two double values, for the task of doing the calculations in Mandelbrot. Specifically, create a version of Mandelbrot that just does the calculations (remove the code that refers to Picture), then create a version of that program that does not use Complex, and then compute the ratio of the running times
